All questions and answers

Read through the full deck, or practise recalling each answer above.

  1. Why is it misleading to use unequal bar widths in a bar chart?

    Show answer

    Unequal widths can make it difficult to compare values accurately, as the visual size/area of bars becomes inconsistent with the values they represent.

  2. What is a common way that dual bar charts can be misleading?

    Show answer

    Using inconsistent scales, missing or unclear legends, or making the bars different widths between the two categories being compared.

  3. What makes a pie chart misleading in terms of angle representation?

    Show answer

    When the angles of the sectors don't accurately represent the proportions of the data, or when the sectors don't add up to 360 degrees.

  4. How can a bar chart with a truncated y-axis be misleading?

    Show answer

    It exaggerates differences between values by making small differences appear much larger than they actually are.

  5. Why might a line of best fit on a scatter graph lead to misleading claims?

    Show answer

    Because it shows only an average trend and doesn't guarantee the exact relationship claimed (e.g., exact annual increases), especially with limited or scattered data points.
